To start, collagen, comprised mainly of the amino acids glycine and proline, is one of the most abundant protein in our bodies, allocating roughly 25% of our total protein mass.

首先，胶原蛋白主要由甘氨和脯氨组成，这是我们体内最丰富的蛋白之一，占我们蛋白的25%。

He showed that the aldol reaction can be catalysed by a single amino acid, proline. And, crucially, this retains the enantiomeric purity of the enzyme-mediated reaction.

他证明了羟醛缩化反应可以被一种氨基--脯氨催化。最重要的是，这保留了酶介导反应的对映体纯。

The researchers found a high concentration of the amino acid proline, which is abundant in dates and some other fruits.

研究人员发现了高浓的脯氨，这种氨基在枣和其他水果中含丰富。

The incorporation of Ascorbic acid with the enzyme, adds hydroxyl group on proline residue in collagen.

抗坏血与酶的结合，使胶原中的脯氨残基上增加了羟基。

And so then I got thinking, Okay, that's I guess possible if you have more glycine and proline.

然后我就想， 好吧，我想如果有更多的甘氨和脯氨的话， 这是可能的。

But it is high in glycine, proline, and hydroxyproline, which makes it very unique in structure.

但它富含甘氨、脯氨和羟脯氨，这使得它在结构上非常独特。

And then I want to say 10% is proline and then another like 10%-ish is hydroxyproline.

然后我想说 10% 是脯氨，然后另外大约 10% 是羟脯氨。

So proline that's had a hydroxyl molecule added to it.

脯氨中已经添加了一个羟基分子。

And then if you look at like whey protein versus collagen and the content of glycine and proline, I think collagen has like three to ten times the amount of glycine and proline in it compared to whey protein.

然后，如果您比较乳清蛋白和胶原蛋白中甘氨和脯氨的含，我认为胶原蛋白中的甘氨和脯氨的含是乳清蛋白的三到十倍。
